Another and a very important object of the in

‘ I also have in 'view the provisionof "a clamp"
for securing ‘the material at its end edge to the

rality of rolls which are supported on the frame
of the'machine.

tension increases rapidly with the number of
layers on the reel and it is when the tension in-v
creases that the loose connection of the bars I5. 20
with the clamp l6 compensates to a very large -
extent for the binding action.

its'opposite. extremities to the two cylindrical

The frame ID of the machine is shown in very
conventional form in Figure 5. This frame may
be varied in numerous ways, its function being.
primarily to support the reel at a convenient
' height and to support one or more rolls of the
50
material which is to be reeled and cut into sheets.
The reel assembly is shown in Figure 1. It
includes arms II projecting radially from cylin
drical members 12 which terminate in the spindles
l3. These arms I I may be provided with calibra
tions as shown in Figure 2 in which the numerals
55 l and 2 may indicate distances from the axis of
and its free' edge is secured by means of the 40
clamp 22. The reel is then turned‘ by hand by
means of the crank 26 so that the material is
wound on the reel. Where only one rolb is em
ployed, one clamp 22 will serve the purpose as‘
the rotationof the reel will always be in the
. same direction. When a number of rolls are sup
ported on the frame H], a secondroll 2? may be
in position such that it will not readily reel but
this difficulty may be overcome ,by the use of
clamps 22 on both sides of ‘a spacer. The
spacer may be the spacer I8 comprising the sev
eral parts as shown in Figures 1, 2 and 4, or it
may be integral as indicated at l8’ in Figure 5.

'marily with Cellophane. Great di?iculty is en 55

secured to said reel and transverse to the plane
thereof, said reel and said web spacing bar having
in common the axis of rotation, menibers having
countered in cutting this material because of its
relative; hardness and because of its peculiar
7 curlin-gf qualities.
A shear action is wholly un
satisfactory anji the number of layers which
a loose connection at the corners of said reel to
can be thus cut is very limited. For this rea
son I provide a novel form of cutting guidewhich
prevent binding of the material during the wind
ing thereof, and a gnide on said web spacing bar
will function with the blade ofiran ordinary jack
knife or any other suitable cutting blade. The
plate 2| is narrower than the plates is and 20,
10 thus affording‘: a channel between the plates. l9
for the insertion of a cutting blade for guiding
the sliding movement of a cutting bladeto out
the webs of reeled material.
and as for the passage of a cutting blade, this
action, it is suf?ciently brittle especially when
under tension to respond readily to the sliding
knife action of a cutting blade sliding in the
20 groove between the plates l9 and 20 of the
I8.
